Aquamarine is a pastel greenish-blue variety of the mineral beryl.. Its name is derived from
the Latin words for water and sea. Crystals form in large
hexagonal prisms. In ancient times, it was believed that
sailors wearing aquamarine pendants would be protected
from the perils of the sea. The stone symbolized happiness
and eternal youth. It was viewed in Christian symbolism
to bring moderation and control of passions to its owner.
It is a gentle and peaceful gemstone, and it is said to
fortify one's sense of self-esteem.
